Keep hazardous organisms out of the body
Physical barriers
Are cells that engulf pathogens and cell debris
Phagocytes
The destruction of abnormal cells by NK cells in peripheral tissues
Immune survaillance
Are chemical messangers that coordinate the defences against viral infections
Inferneurons
Is a system of circulating proteins that assists antibodies
Complement system
Is a localized tissue-level response that tends to limit the spread of an injury or infection
Inflammation
Is an elevation of body temperature
Fever
Nk cells sensitive to the presence of abnormal plasma membranes are primarily involved in
